       A YANG Data Model for Client Signal Performance Monitoring
                  draft-zheng-ccamp-client-pm-yang-02

Abstract

   A transport network is a server-layer network to provide connectivity
   services to its client.  Given the client signal is configured, the
   followup function for performance monitoring, such as latency and bit
   error rate, would be needed for network operation.

   This document describes the data model to support the performance
   monitoring functionalities.

1.  Introduction

   Client-layer network and server-layer network have been respectively
   modeled to allow the tunnels carrying the client traffic.  Server-
   layers are modeled as tunnels with various switching technologies,
   such as [I-D.ietf-ccamp-otn-tunnel-model] and
   [I-D.ietf-ccamp-wson-tunnel-model].  Client-layers are modeled as
   client signals according to the client-signal identities specified in
   [I-D.ietf-ccamp-layer1-types].  These client signals can be
   configured to existing tunnels via the client signal configuration
   model specified in [I-D.ietf-ccamp-client-signal-yang].

   In the network operation, the operator is interested in monitoring
   for their instantiated client signal over tunnels.  The objective for
   such monitoring is to complete timely adjustment once there is
   abnormal statistic which may result in failure of the client signal.
   The parameters specified in the performance monitoring model can be
   collected for the operation need.  The OAM mechanism, can be
